What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The check engine light illuminated and the engine began running rough with misfires. Stored fault codes included P0301 and P0302 (cylinder 1 and cylinder 2 misfire detected) and P0315.
While driving, the panoramic sunroof on my 2020 Mercedes-Benz CLA250 4MATIC shattered unexpectedly while fully closed. The interior sunshade was also closed at the time. There was no prior damage and no discernible impact. I did not observe or hear anything strike the vehicle.
What to check before buying

- Visibility. Wipers, mirrors, defrosters, cracked glass.
